State employees are raising money for the family of Nathan Leon. The pizza deliveryman was killed last month in an attack authorities believe is connected to the murder of Department of Corrections chief Tom Clements.

Gov. John Hickenlooper on Thursday announced an audit to ensure the state’s prisoners are serving their correct sentences, two weeks after a parolee who was mistakenly released four years early was identified as a suspect in the killing of Colorado’s prisons chief.

Two more men connected to a violent white supremacist gang are being sought in connection with the slaying of Colorado’s prisons chief, according to a warning bulletin that’s the first official word other gang members might be involved.

The ex-convict suspected in the killing of Colorado’s prison chief who was mistakenly released from prison four years early slipped off his electronic monitoring bracelet, but parole officials didn’t realize he had fled until just hours before the slaying.

Colorado court officials have vowed to review procedures to ensure that a clerical mistake that allowed the early release of a prisoner — who then went on to allegedly shoot the state’s corrections director last month — doesn’t happen again.
